The summariseChanges function in 1.1 sends out a limited diff of the changes, not the complete change. Is this sufficient for this task? Please check out the notification e-mails coming from Foswiki.org since late yesterday. (The diff function was broken previously)

The current diff mode actually is limited to 70 characters per line and 6 lines total. So a feature request might be to make these limits (currently CONSTANTs in Foswiki::Meta ) controllable by additional parameters to Func, and either configurable in the preferences, or settable in the LocalSite.cfg. Preference variables would probably be more difficult since they are per web / user / topic while the emails are I believe generated for multiple users.
